Abstract
Two glucosyltransferase isozymes from Phytolacca americana, PaGT3 and PaGT2, catalyzed stereo- and regio-selective monoglucosylation of 3,5,3',4'-tetrahydroxy-trans-stilbene to yield 3,5,3',4'-tetrahydroxy-trans-stilbene-4'-O-beta-D-glucopyranoside.
摘要
来自美洲商陆的两种葡糖基转移酶同工酶，即美洲商陆葡糖基转移酶3（PaGT3）和美洲商陆葡糖基转移酶2（PaGT2），催化3,5,3',4'-四羟基反式芪的立体和区域选择性单糖基化反应，生成3,5,3',4'-四羟基反式芪-4'-O-β-D-吡喃葡萄糖苷。
